Definitions

  • the sixth invention since the number of notches of the impeller blades arranged in a range corresponding to the electrical component box is small, it is possible to suppress a reduction in the air volume.
  • the eighth invention since the number of notches of the impeller blades arranged in the range corresponding to the auxiliary filter is small, it is possible to suppress a decrease in the air volume.
  • the straight portion 32a of the hairpin tube 32 is inserted through the through holes of a large number of fins 31 arranged in parallel at equal intervals.
  • the linear portion 32a and the fin 31 are fixed by pushing the tube expansion jig having a slightly larger diameter than the linear portion 32a into the linear portion 32a to expand the linear portion 32a.
  • the tube expansion jig is pulled out from the hairpin tube 32.
  • the fin pitch of the plurality of fins 31 on the curved portion 32b side is narrower than the fin pitch of the other portions.
  • the blower 20 includes a plurality of impellers 21 disposed on the same rotation shaft, a plurality of annular plates 23 disposed between adjacent impellers 21, and a plurality of blades.
  • Circular end plates 25, 24 arranged at the left and right ends of the vehicle 21 are provided.
  • a cylindrical boss portion 24 a into which the rotation shaft of the fan motor 44 is inserted is provided at the center portion of the right end plate 24 so as to protrude rightward.
  • a shaft portion 25a supported by a bearing portion 3c (see FIG. 4) formed on the main body frame 3 is provided at the center portion of the left end plate 25 so as to protrude leftward.
